i386: Fix PR97715
This change fixes a bug in the i386 backend when adding
-fzero-call-used-regs=all on a target that has no x87
registers.
When there is no x87 registers available, we should not
zero stack registers.
gcc/ChangeLog:
PR target/97715
* config/i386/i386.c (zero_all_st_registers): Return
earlier when the FPU is disabled.
gcc/testsuite/ChangeLog:
PR target/97715
* gcc.target/i386/zero-scratch-regs-32.c: New test.
